    <p>I'd like to use JPA 2.0 with EclipseLink (2.4.0) and sqlite 3.7.2 in a simple Java Swing application.</p> <p>The first thing I have encountered is, that EclipseLink doesn't support sqlite. Here is the output:</p> <blockquote> <p>[EL Info]: 2012-09-18 18:05:42.246--ServerSession(31125695)--EclipseLink, version: Eclipse Persistence Services - 2.4.0.v20120608-r11652</p> <p>[EL Info]: connection: 2012-09-18 18:05:42.352--Not able to detect platform for vendor name [SQLite3]. Defaulting to [org.eclipse.persistence.platform.database.DatabasePlatform]. The database dialect used may not match with the database you are using. Please explicitly provide a platform using property eclipselink.platform.class.name.</p> </blockquote> <p>However, it seems to me, that the configuration works almost fine.</p> <p>But when I have a model with related Entities (i.e. @ManyToOne) the tables can't be created automatically.</p> <blockquote> <p>[EL Warning]: 2012-09-18 18:05:42.629--ServerSession(31125695)--Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.4.0.v20120608-r11652): org.eclipse.persistence.exceptions.DatabaseException Internal Exception: java.sql.SQLException: [SQLITE_ERROR] SQL error or missing database (near "CONSTRAINT": syntax error) Error Code: 0</p> <p>Call: ALTER TABLE blub ADD CONSTRAINT FK_blub_customer_id FOREIGN KEY (customer_id) REFERENCES customer (customer_id)</p> <p>Query: DataModifyQuery(sql="ALTER TABLE blub ADD CONSTRAINT FK_blub_customer_id FOREIGN KEY (customer_id) REFERENCES customer (customer_id)")</p> </blockquote> <p>As you can see, the additional creation of foreign key constraints isn't supported by sqlite.</p> <p>Do you have any idea how to fix the problem?</p> <p>Best regards</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
